' Specification of Letters Patent. Patented Oct. 30, 1191 7,

- Application filed November 17, 1916. Serial No. 131,877.

To ell 107mm it may concern. s 4 .Be it known that 1, Josnrn' SACHS, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Meter-Testing Appurtenancesy of which the following is a specification. I 7

y This invention relates to a meter testing appurtenance by' which I can in a ready,

"quick and accurate and very inexpensive manner obtain a metertest. There area large variety of embodim'entsof the apps ratus which it is unnecessary for me to illustrate and describe.

statute -I have shown one form of apparatus which'lias met my conditions in an-eminently satisfactorymanner. This I will set forth in detail in the following description.

Obviously I am restricted in no senseto this particular disclosure; I. may depart--therefrom in radical respects within the scopeofthe invention defined by the claims'followingzsaid description,

eferring. to: said drawings: Figure 1 is a diagrammatic view of a meter installation incl-udlng a form of meter testing appurtenance.

Iso

Figs. 4 and 5 are front. views of the portions of said appartenance-separated.

Figs. 6 and? are end views of said portions separated.

Fig. 8 is about view of a portion'of-thc meter-including ameter terminal and showing the appurtenance'connected therewith.-

Fig. 11 is a similar view with the portions ofthe testing appurtenance separated.

Fig; 12 is a lilge view showing the'connection of the meter in circuit with testing devicesafter' the circuit has been by-passed around the meter and the connection be tween the circuit wire and the meter separated.

Like ch ara cter's refer to like parts through out the several views which new different v scales.

To comply with the I provide a meter testing appurtenance which is susceptible of very inexpensive manufacture, which can be incorporated in a ready, quick manner in any meter installation and by which any of the well-known' meter tests can be performed. Thisappurtenance in that particular form thereof which I have-chosen to select for illustration in my drawings comprises two portions or elements electrically connectible and disconnectible In the present case the'electrical connectlon is eflected mechanically: One of these portions is adapted for connection with a meter terminal in such'way that I can not only obtain the necessary electrical connec-.'

tion butcaii effect the necessary mechanical support of the appurtenance in its entirety.

The other element or portion has provision for the connection therewith of a circuit wire (generally aload wire).' The two pora tions as herein shown are each provided withmeans for the connectiontherewith of a testing device. For the purpose of earryin out the particular testing pr'ocedureas illus trated in Figs. 10 to 12 inclusive the circuit 1 V wire connected portion receives or connects 'Wlth a test ng by pass whereby the circuit is passed around the 'meter 'while the portion connected with the meter terminal receives a-testing device serving to include in circuit with the. meter the testing instruments.

While there is certainly an element of advantage in providing a sectional, appur- *tenance such s that I'have briefly described,

I am in no sense limited thereto as the invention is broader than this, as will be gathered from an inspection of my claims.

\Vhile in the particular test procedure and for the performance of the particular testshown in Figs. 10 to 12 inclusivea by-pass is electrically connected to one of. the portions, while the testing instruments are electrically connected with the meter terminal through (inthis instance) the other portion of the appurtenance. it will be clear that for" the performance of other tests the appurtenance may be otherwise connected, as for instance instead of. using av by-pass to jump around the meter and then include the meter in a separate testing circuit with separate testing instruments and testing load as is illustrated in said views, the testing meter alone may beconnected directly in circuit with the installed meter'end load bycon-- necting the terminals from thetcsting meter respectively to each of the two portions of the. appurtenanee already referred to.

Referring now more in detail to Figs. 2 to 7 inclusive'wherein I represent the. appu'rtena-nce in assembled and separated relation. For convenience this 'a-ppurtenance will be denoted in av general way by 2 As illustrated said appurtenancecomprises two port-ions, members or elements as 3 and 4 respectively. The made or may be made from sheet metal, suchas brass or copper.

comprises a body from whichthere extends 1-5 -a tongue 5 which may as shown be in the plane ofthe body. The body of said element 3 is provided with'suitable means for the connection therewith of a testing appliance and the offstanding flange or blade 6 at the outer end of factorily in this particular, this blade or ifiange being V clip terminal of such a testingappliance, or itmaybe otherwise connected therewith.

As will be clear, this ismerely one of several ways by which the necessary connection with the portion 3 made. The portion 4 as will hereinafter appear-is-adapted for conne'ctionwith a circu' t wire, and Iivillset forth a simple way ofseveral by which this particular result can be obtained. In addition to the fact that a circuit wire (which maybe either a load wire as shown or; otherwise); is con- 35. nected to' the portion or member4 or analogouselement, there is provision for the connection therewith of a, testing device ;which in the test shown is aby-pass or jum-per. This by-pass or jumper may be 40 electrically (and mechanically) connected -'with thepart 4 or its equivalent in any de- 'sirable manner. For instance and shown,

' said part4 may" standing blade or flange as 7 to receive a clip terminal other testing instrumentality. The two portions Oftheappurtenance-may be mechanically and electrically connected for mechanical andelectrical si'on arises therefor i'n'any' suitable manner.

The means 'illustratcd for this purpose answers, and I will now set forth the same. The inner'end of the portion or element 4 has'a slot-8. which as shown is open at one 55, end. This slotted'partof the portion 4 .lits flatwise against the 3 as illustrated for instance ii-rboth Figs-'2 and 3, the two-portions being held asselnbl wl by the screw?) tapped intothc body of lhe part 3 and the head of which I slotted part' of the portion 4- against the body of the portion The slot being open.

il heroines a simple matter to separate morhanically and electrically he two portions i and -l-. .This-is-accomplished by slightly portion or element 3 As represented it.

the body answers satisadapted to be straddled by a" will, however,

or its equivalent can be' installed meter,

be furnished with an ofl' of the lay-pass or jumper or disconnection when occabody of the portion chun 'is the.

terminal 1R.

from the supply wires to the load wires whether such current supply is. by passed around the meter by a bypass as shown and the meter tested in a separate t ting circuit or whether the installed meter is always included in the supply circuit and the testing meter inserted in said circuit or by any other arrangement of connections. In the form of my meter testing appurtcnance herein illustrated, I have shown a meter connecti'ble portion and a circ'uitwire connectiblc por tion, the two'portions being mechanically separable in order to effect their electrical disconnection -.for the purpose stated." It be clear that there'are various waysof accomplishing the electrical separation desired without mechanically moving the two portions one from theothelx. The, circuit wire connectible portion 4 is provided with means of some convenient nature for theconnection therewith of a circuit wire.

At times, ho.\\evcr tl 1c meter installation '|"||a be of radicall) different arrangement. In the showing heroin I simply' illustrate a. service side appliance for the purpose of indicating some form of service side crmncrtmlaopliancc or (t()IlIl OC-- tion for obtaining pr per service side conncction in. making ccrlaiu tests \vhore for instance lhc Irv-pass or jumper testing dcyicc' is'uscd. I lu lrigr. H T. ha \0, shown a portion of the terminal (chamber of the motor including one ol the connecting terminals T8 of tho' motor. The motor testing appurtenance of my invention is shown electri ally connected to and lmrchanically supported by said I in the particular uu-lrr install and under ttfilr. In to It! inclusive,-

.lcstiug appurieuunor associated with only our ul 'tllc u|( and 13 and load wires as 14:..-

- ter terminals. It will be clear,-however, that I'may employ'more than one. For instance, I may have such an appurtenaince in asso ciation with a load side lneter terminal and another appurtenance in association with a :service side meter terminal, both ofwhich lar test the circuit is jumped or by-passcd '"around the meter from the service to the load side circuit wires, while the meter previously included undernormal conditions between these two points or at least the cur- 5 rent'c'oilof the meter is now disconnected from its prior load side connection and included in a separatetesting' circuit having .the'test-ing instruments-and load. Itis well understood, however, that there are various other forms-of testswhich it may be desired to perform. in connection with the particu lar mcterin'stallation illustrated in Fig. ,1;

for instance as has already been stated in-. steadof including the meter or; its current coil ina-separate testingcircuitand bypassingaround the ineter'from the service to theload circuit wires, it maybe desired,

to connect directly in serieslwith the in- '-=stal led meter and load the testing meter. My testing appurtenance is adapted for the f ter, then it-i's desirable touse a testing performance of either formjof test, or any 'other.'- Where the testis to be made by bypassing onjumping around the installed mef jumper or by-pass" as 1 9'fitted with clip terminal 20 at one 'end forthe association and isconneoted with the'appurtenanc'e portion 4. Consequently that particular leg of the circuit includes the .service circuit wire 12,

" the clirr'ent coil 16' of the meter, the meter testing'appurtenance 2 and the load circuit v i i to be electrically connected to and niechanielectrical connection with the blade 7 of the portion 401 any other similar or equivalentk part of my-ap'purtenance. The other terminal 21 of the by-pass may be of any desired form for thei connection of this terminal with the service side appliance. In the organiiatioii shown in ig. 1 the load wire 15 wire 16.

In making the particuar form of test -illus-- trated in Fig: cedure may .10 to 12, th e following pro adopted: The testing by-pass 19 is "first connected across'from theeload circuit wire connected portion 4 to the service side-appliance 17 as shownin Fig, 10 so that the meter coil 16 is now shunted or bypassed. Qrdinarily although a different procedure may be used, 'the'two'portions of the testing a'ppurtenance are now separated in the manner alreadydescribed, and the load circuit. wire connected portion 4 is bodily -moved'away from the meter terminal connected portion 3, thus breakingthe elec' 3 to the load side through the meter coil 16 trical connection between the meter terminal and the load wine but Without interrup tion ofthe circuit from the service-to theload circuit wires, which is maintained through theby-pass. This separation by bodily moving the portion '4 and its connected circuit wire 15 is reinescnted in Fig. 1]. To now'lest the meter, it is necessary to put the coil 16 in circuit with certain testing instruments which'usua'lly include a resistance testing load24 and a standard meter;

' testing meter 25. The testing lead or cable 26 sci-res as one terminal of the testing instru ments and is fitted with theterminal 27 which maybe like the clip.2'0 of the bypass 9 to'be engaged in straddling connectionwith the blade 6. The cable 30 from the other end of the testing instruments is then connected to the other leg'of the circuit ahead of the i 'meter as indicated 'at'3l. Connections from the potential coil of the'standard meter may.

be made in thewell-known manner as indifrom .the blade 6 and the two portionsof. the testing appurtenance may be connected together electrically and mechanically after which the by-p'ass may -be removed and the current then again passing from the service as shown in Fig. 1.. a
